Tesla Roadster is Genius, And Here's Why


Tesla jumped into the Electric Vehicle game with its first-generation Tesla Roadster. And it would not be wrong to say that Tesla Roadster put Tesla on the map. And that’s not the only historic thing about the Tesla Roadster. It also has the honor of being the first car in space. As part of a flight test for SpaceX falcon heavy, it was revealed that the reusable rocket was carrying a Tesla Roadster in its nose cone. The cherry-red electric sports car belonged to non-other than Elon Musk himself. Its stereo was programmed to play David Bowie's Space Oddity and there was a big DON’T PANIC text display on the screen display. It's a reference to the words on the cover of the famous science fiction book “The Hitchhiker's Guide to the Galaxy” by famous American writer Douglas Adams.
But returning to earth, let us look at what makes the Tesla Roadster the marvel of engineering and what exciting things can we expect from the second generation of Tesla Roadster coming out next year.
The history of the original Roadster
Tesla released the first generation of Roadster in 2008, and it came with a range of 245 miles or 394 kilometers on a single charge. This kind of range was unheard of for battery electric vehicles back then. Not only that, but real-life performance tests also showed that its performance was comparable to that of many gasoline-powered sports cars: The Roadster could accelerate from 0 to 60 miles per hour in less than 4 seconds and could reach a top speed of 125 miles per hour [1]. Combine that with the fact that the Roadster produced no tailpipe emissions, the Car was an immediate hit.
The body of the car was made of carbon fiber to make it as lightweight as possible. And since it was a fully electric vehicle and didn’t use an internal combustion engine like the other cars of the time, there were no tailpipe emissions. The car was clean, it was fast, and it looked sexy!
Elon Musk himself got the first-ever Tesla Roadster made. The company produced 500 similar vehicles through June 2009. Tesla would go on to sell about 2,450 Tesla roadsters in over 30 countries all over the world. An interesting fact is that most of the Roadsters were sold in Europe and Asia. Even with a government incentive such as a $7,500 tax credit, the first-generation roadster cost $ 109,000, making the car more of a luxury vehicle.
The secret sauce behind Roadster’s performance and its range was just one simple thing, Tesla’s proprietary storage solution. This was a 200-kWh battery pack. It was composed of 6800 tiny 18650 lithium-ion cells. The naming convention of these cells is based on their physical dimensions. A 18650 cell is 18mm in diameter and 65mm in length. Using small lithium-ion cells and combine them to make a large battery pack was unheard of back then.
In fact, J. B. Straubel, the mastermind behind Tesla’s energy storage solutions and the battery pack, in his 2006 paper explains the reasoning behind using small lithium-ion cells that were previously just used in phones and laptops. Straubel said.
“We started our design by purposely picking a small form factor battery cell. Due to its small size, the cell contains a limited amount of energy. If a failure event occurs with this cell, the effect will be much less than that expected from a cell many times larger.” [2]
And since then, Tesla has been using the same formula, developing small lithium-ion cells, and combining thousands of those to make a big battery pack.
The first generation of the roadster was Tesla’s way of testing the waters in terms of both their technological capability and how the public would receive a fully electric vehicle. And on both sides, it was a great success. The same battery technology that Tesla developed for the Roadster would go out to set an industry standard for what is to be expected from an electric vehicle.
